Abstract:
|
In this paper we study the design of a wireless sensor network in a spatial temporal domain for optimal parameter estimation. We consider the setting where we are given a set of potential sensor locations, a parametric model for the process being monitored, a cost constraint, and a communication protocol, and our objective is to design a sensor network to deploy at a subset of these locations, and use the data collected from the network to estimate parameters of the underlying process. We formulate the problem as maximizing a D-optimal design criterion for parameter estimation under communication and cost constraints. Both linear and nonlinear models are considered, and we provide a general framework to include a variety of practical cost consideration in the constraints. Algorithms based on generalized semi-definite programming are developed to find the optimal design under constraints.
